ANTIREFILLING DEVICE.

SPECIFICATION forming part of Letters Patent No. 606,026, dated June 21, 1898. Application inea Tammy 1o, 189s. serai No. 666,167. No man To all whom t may concern:

Beit known that I, JOHN H. POOLE, of Randolph, in the county of Norfolk and State of Massachusetts, have invented lcertain new and useful Improvements in Antirelling Devices, of which the followin gis a specification.

This invention has for its object to provide v position for pouring. Fig. '3 represents a similar view showing the bottle-neck in a horizontal position. Fig. 4t represents a section on line 4 4 of Fig. 2. Fig. 5 represents a modification. Fig. 6 represents a view similar to Fig. 4., showing the casing provided with a com pressible sleeve.

The same letters of reference indicate the same parts in all the figures.

In the drawings, c represents a tubular casing, which may be of glass or other suitable material and is adapted to be inserted inthe neck h of a bottle. casing c is a collare, which is formed externally to close the inner end of the casing and is perforated centrally to`form a valve-seat a. The collar a projects a considerable distance into the casing c and is internally enlarged above the valve-seat to form a valveguide and is reduced or tapered externally within the casing, so that its outer surface and the adjacent portion of the inner surface of the casing form an annular pocket d, surrounding the valve-guide and intended to receive the end of a wire or other device fraudulently inserted in the neck of the bottle, as hereinafter described.

e represents a ball-valve, which is formed to fit the seat a and close the port surrounded by said seat. The said valve is adapted to roll in the valve-guiding portion of sleeve Ct toward and from the seat a.

g g represent stops or projections formed on the inner surface of the casing c between At the inner end of the' the inner end of the sleeve a and the outer end of the casing. l j

. firepresents a loose spherical ball-guard, which is of larger diameter than the interior of the sleeve a and is adapted to play between the inner end of said sleeve and the stops g g, the said stops'being formed to limit the outward movement of the guard f. Vhen the bottle is tipped for pouring, as shown in Fig. 2, the guard f rolls outwardly far enough to permit the valve e to partly, but not wholly, leave the sleeve a, thus permitting liquid to ow from the bottle through said. sleeve, the liquid escaping around the ball through the spaces between the stops g, said spaces being shown in Fig. 4. When the bottle is held in a horizontal position, as shown in Fig. 3, the guard f is caused by the inclination of the stop g at the lower side of the neck to roll inwardly lfar enough to push the valveinto the sleeve a, the valve then occupying such position that it will be moved along the guide and pressed against its seat by the pressure of liquid forced into the neck while the bottle is in this position. :When the bottle is upright, the guard f rests on the upper end of the collar a and covers the valve-guide, as shown invFigs. l and 6.'V

y It will be seen that while the guard f is of lesser diameter than the interior of the casing between the stops g and the collar a its diameter is such that a wire or other flexible device fraudulently,inserted with the intention of displacing the valve e is deflected by the guard into the annular pocket CZ and is thus prevented from gaining access to the valve.

I prefer to make the sleeve a in a separate piece from the casing c and insert it in the casing, a rigid connection being formed between the sleeve and the casing by any snitable means. If desired, however, the sleeve may be formed to bear at its outer portion on the interior of the neck of the bottle, as shown in Fig. 5. l

In Fig. 6 I show the outer end of the sleeve c provided with an outwardly projecting flange c2, adapted to bear on the interior of the bottle-neck. Below said flange the casing is provided with a sleeve c3, of compressi! ble material, such as cork. Said sleeve is IOO originally of sueli diameter that when inserted `in the bottle-neck it will be compressed, and

wall of an annular pocket surrounding the l valve-guide; secondly, a ball-valve formed to move in said guide and fit the valve-seat; 4

thirdly, stops attached to the bottle-neck above the valve seat and guide; and fourthly, a loose spherical valve-guard adapted to play between said stops and the outer end of the valve-guide, said guard being of greater diameter than the valve-guide and adapted to' deflect a Wire inserted in the bottle-neck into 1 said annular pocket, the guard being proportioned to permit a liquid-releasing movement of the valve and to prevent the escape of the valve from the valve-guide. ln testimony whereof I aix my slgnatu re in presence of two witnesses.
